Specification of Letters Patent.

Patented 001x22, 1907 Application filed September 24 {1906' Serial No. 335,915.

To all whom it mat concern:

Be it known that I, HARRISON Rrcrr, a citizen of the Uni ted States of America residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Windows; 7 andl do hereby declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relatesto improvements in windows, and its object is to provide improved means for readily removing and replacing the sash; to provide the device-} with. improved means for supporting and balancing the same; to provide improved "means for preventing air 15, from passing through the joints thereof; and to provide the same with various new and uselulieatures hereinafter more fully described and particularly pointed out in the claims. reference being had to the accompanying drawings, in which: I Figure l. is a front elevation of a device embodying myinvention with parts broken away to show the construction; Fig, 2. a vertical section of the same showing an elevation of one side of the ease with the slides therein; Fig. 3. an enlarged detail in horizontal section on the line 3-3 of Fig. l pFig. 4 a detail of the casing strip;

' Fig: 5. a detail of one of the slides; Fig. 6. a perspective detail of a portion of a sash; Fig. 7. a detail of the keyhole plates for holding the stops; Fig. 8. an enlarged detail of the slide holding and supporting mechanism; Fig.

9'. the same at right angles to Fig. 8.; Fig. 19 a detail of l the spring catch to hold the sash in place on the slides; Fig. 11. a perspective detail of the slide holder; Fig. 12 a'detail oi the means for attaching the ribbon support to the slide.

Like numbers refer to like parts' in all of the figures.

1 represents the upper sash and 2 the lower sash of the window, each provided with recesses 3 in its lower corners to receive supporting pins 4 projecting inward from the lower ends of slides 5 formed of sheet metal and 4C adapted to traverse vertical grooves in the casing oppo' site the respective sides of the sash and adjacent thereto and provided with inwardly projecting members (i at the top and having openings adapted to receive upwardly projecting spring stops 7 inserted in the sash, and thus to secure the sash in place between the respective slides 5. To support these slides and balance the -weight thereof together with the sash supported thereby, metallic ribbons 8 0r cords 8 are attached to the slides and extend upward within the grooves for the slides and thence over sash pulleys 9, and have attached I thereto counterbalance weigh ts 10. The inner edges of the slides =3 are slid-ably inserted in channel strips ll formed of sheet metal folded around the inner edge of each slide a nd secured Within the grooves of the casing.

The outer edge of the slides 5, to stiffen the same and form freely sliding and air-tight joints, are folded to form matter of appearance.

channels in which are inserted the edge of weather strips 17 secured to the sash. The slides 5 thus engage and traverse the channel strips at one edge and are flexibly engaged with the weather strips 17 at theother edge, whereby they readily conform to any slight variation in the space between the side of the sash and the casing, and at the same time provide a joint therebetween that will keep from passing therethrough,-

To form a finish, stops 12 may be provided which I detachably hold in place by means-of screws 13 inserted therein and projected through key-hole slots in plates 14 attached to the casing. These steps are short at the top so that theycan be-readily detached by moving them upward whereby the heads of the screws will pass through the enlarged openings at the upper ends of said slots. These stops, however may be omitted without materially affecting the operation of my devicein which event the sashes are freely removed and inserted within the slides by merely detaching the spring stops 7 from the inwardly projecting cndsti'of the slides and moving the upper end of the sash inward clear of the said ends and lifting it off the pins 4. Opposite the uppoisash and terminating near the bottom thereof, stops 12.1 nay bealso used if preierred, and these stops need not be detachable. The upper sash can be removed by lowering the same below the bottom of these stops after the lower sash has been removed, but these stops also may be omitted as they are not necessary except for the When the sash is removed, the weights would overbalance the slides and carry the same upward. To prevent this, I proi'i de automatic stops to hold the slides when the sash is removed. For this purpose a shoulder 15 is formed in the rear of each slide and a spring hook 19 is provided in the casing to engage this shoulder and hold the slide from moving up-' ward. When the sash is inserted in place, these hooks are automatically released by means of lugs 18 formed on the weather strip 17 and projecting therefrom sufficient to enga e and move the book out of contact with the shoulder -15, thus rendering the hook inoperativ when the sash is in place.

To attach the sash cord to theslide, I provide a hook 16 on each slide struck up from the slide and'projqcting within the channel in the casing and inserting the end of the cord 8 in a tapered or conical socket 20; forming a knot or enlargement in the end of the cord within the socket, and providing an eye 2]. on the socket to engage the hook 1.6. If a ribbon is used, a link 22 is secured to the end of the ribbon, which serves to engage the hook l6 and attach the ribbon thereto. 4

.Whut l claim isd l 1. In a window, the combination of a casing, channel strips fixed in the casing, slides having one edge slldable in the channel strips and a groove in the otheredge, a sash, weather strips on the snsh and engaging the grooves. in the slides, and means for detachably connecting the sash and slides.

2 I seems 2. In a window, the combinatlon' of a" casing, strips of sheet metal folded to form a channel and attached to the casing, sheet metal slides each having one edge slidable in one of .the channel strips, and the other edge folded to form a groove, a sash weather'strips attached to the sash strips folded to form channels and fixed'in the c asing, slides each having one edge 'slidable in one of said (.hannelsjand' the other edge folded to .torin a groove, pins in the lower ends of said slides, a sash having recesses to receive the I pins, spring stops in the sash and engaging openings in the upper ends of the slides, weather strips attached to thesash and engaging the grooves in the slides, and means for counterbalancing the slides and sash. 4. In a window, the combination of a casing, slides'vertically movable in the casing and having shoulders, spring hooks in the casing and engaging the-shoulders, a sash, means for detachably connecting the sash and slides, lugs 'on the sash to engage the spring hooks and disengage them from the shoulders, and counterbalance cords and weights attached to thesiides. e r 5. In a window, the combination of a casing, sheet metal slides in the casing and having 1'olded edgesv tormlnz connected to the slides.v
